5f875e3393 chore(web): address Copilot review on #2153
- Publish `setupClientForServerRef` from a layout effect rather than during
  render. React runs every layout effect before any passive effect of the same
  commit, and the /oauth/callback effect is passive, so the seam is still
  published before its first read — without the render-phase ref mutation the
  compiler rule rejects. This was the one `react-hooks/refs` finding the PR
  introduced, so its suppression is gone rather than deferred to #2161 under a
  justification that did not describe it.
- Narrow the hook's `fetchLogRef` option to `FetchRequestSource`, the
  `getFetchRequests` slice it actually consumes, mirroring
  `InspectorClientEventSource` in useProgressToasts. That removes the test
  harness's `as unknown as` cast, and the narrowed contract is real: it
  immediately rejected the loosely-typed fixture, which is now a properly typed
  `FetchRequestEntry`.
- Make the test harness hold both refs across renders and publish them from a
  layout effect, as App.tsx does. The deferred-publication test previously
  passed because `Probe` built a fresh ref each render and the rerender also
  changed `servers`; it now asserts what the guard is actually for — a run that
  cannot exchange must not spend the single-use code — and re-triggers on the
  `servers` change that carries it in production.

ed38a5e5fe chore(web): extract App.tsx's OAuth recovery cluster into useOAuthRecovery (#2153)
Phase 2 step 2 of the App.tsx decomposition (#2129, under #2126). App.tsx goes
from 4,267 to 3,178 lines; no behaviour change.

The new hook owns the step-up slot and its retry operation, the re-auth banner,
the deferred background-tab recovery, the redirect plumbing (webOAuthStorage,
sessionStorageAdapter, onBeforeOAuthRedirect, prepareOAuthRedirect), the
command-scoped recovery wrappers, the four OAuth effects, the abandoned-redirect
check, the /oauth/callback completion, the Connection Info OAuth details, and
the clear/finalize paths. All five once-only latches move with it unchanged.

Three seams could not be a straight move:

- useSessionRef no longer takes pendingStepUp/pendingReauth. They are this
  hook's own state, so App.tsx would have had to hold them purely to hand them
  back; instead the owner mirrors them into the ref in an effect of its own,
  following the shape activeServerName already had.
- setupClientForServer is injected through a ref, because it reads
  onBeforeOAuthRedirect and sessionStorageAdapter out of this hook and so
  cannot be declared before it. The callback effect reads the ref before
  burning its one-shot latch.
- The two clear-OAuth modal adapters and onReauthenticateFromBanner stay in
  App.tsx: they bind App-owned state, and the latter drives a reconnect, which
  step 3 owns.

Dropping ~1,100 lines took App.tsx under the React Compiler's bail-out, so the
compiler-backed react-hooks rules now analyse it and report nine pre-existing
findings that were previously invisible. Each is suppressed with a narrow
justified disable naming #2161, which is filed to resolve them; the one new
finding (exhaustive-deps on setReAuthBanner) is fixed rather than suppressed.

9ddbec56f2 ci: rename the workflow to CI, and fix a README line this PR made stale
The old name — "Run install, format, lint, build, and test on every push" —
enumerated steps rather than naming the workflow, and was wrong in two
directions: it never mentioned the coverage gate, and "on every push" reads
past the two release-gated publish jobs. `CI` renders as `CI / build` and
`CI / coverage` in the checks list, where the job name already carries the
detail.

Display-only: nothing references the name (no badge, no `workflow_run`, no
sibling workflow), and branch protection keys off JOB names, which are unchanged.

Also: README described the publish jobs as `needs: build`, which the previous
commit falsified.

9cd06598a4 ci: run the coverage gate in a parallel job (#2159)
`build` ran `npm run validate` and `npm run coverage` back to back, and on a
recent green run those two steps were 84% of a 17m9s wall clock (7m41 + 6m50).
They are serial for no reason: `coverage` consumes nothing `validate` produces.
Every client's `test:coverage` is self-sufficient — web and cli build the test
servers themselves (cli its own bin too), tui and launcher run from source — and
the only consumers of `clients/*/build` are the smokes, which stay in `build`
alongside the `validate` that produces them.

So split `coverage` into a sibling job. Both publish jobs become
`needs: [build, coverage]`: that is the safety property, not a side effect —
left as `needs: build` a release could publish with the coverage gate red.

Deliberately NOT backgrounding the two inside one job: that puts two vitest
fleets on one 4-core runner, which already times tests out at the 5s default.

Wall clock ~17m -> ~10m, for one extra runner and a duplicated ~24s install.
Splitting `coverage` per client is the next lever and stays out of scope.

e15dd8abee fix(scripts): make the test stubs drain, and the raw-mode guard testable (#2147)
Copilot review round 5 — four findings, all in the suppressed block.

1+4. The regression stubs did `console.log(MARKER); process.exit(1)`.
     Writing to a PIPE is asynchronous and `process.exit()` tears the
     process down without draining, so the marker can be lost outright —
     and then the stub that pins the paint-then-die path fails as "exited
     before rendering", the neighbouring branch and the wrong diagnostic
     for the thing it guards.

     Worth recording that I met this mechanism last round and did not join
     the dots: probing the drain race, a 4MB write followed by
     `process.exit()` reached the parent with the marker missing
     entirely. That was noted as a reason the repro failed, while the same
     construct stayed in the stubs. Both now set `process.exitCode` and
     let the loop drain — still exiting immediately after the write — with
     a comment, since `process.exit()` is the more obvious spelling and
     will read as a simplification to the next person. Same fix for the
     `console.error("boom")` stub, whose assertion had the same exposure.

2.   DEFAULTS claimed "every one is a hard floor as well as a default",
     which contradicts `normalizeMs` (any finite positive value passes)
     and the suite two files over, which passes 400ms against a 2000ms
     default. It rejects the shape a bad env var produces, not smallness.

3.   The raw-mode forbidden-output check was unreachable from any test:
     the real PTY happy path only exercises the pattern NOT matching, so
     a regression breaking it would stay green forever — an
     acceptance-criterion guard with nothing guarding it, which is the
     recursive form of this PR's own complaint.

     Now a `runRenderSmoke` option (`forbidOutput`), so it runs inside the
     tested state machine and against the fully drained output.
     `smoke:tui` passes its pattern in and drops the post-hoc check. It
     can only turn a pass into a failure, never rewrite an existing
     failure's message: a crash reason is more useful than "and it also
     printed X", which is usually a symptom of that crash. Three tests —
     matching, not matching, and that asymmetry.

Verified: test:scripts 213/213; `smoke:tui OK — rendered "MCP Servers" at
360ms and was still running 2000ms later`; and the no-PTY shim still
fails through the refactored path.

4af38c719c fix(scripts): don't arm a survival timer after the verdict is settled (#2147)
Copilot review round 4.

`exit` can be observed before the child's last output drains — `done()`
already keeps reading until `close` for exactly that reason — so `onData`
can run after the verdict is settled. Recording `markerAt` there is still
right: the message is a thunk rendered at `finish()`, and a marker still
sitting in the pipe when `exit` fired was painted all the same. Arming a
survival timer is not. It could not change the result (`done` is a no-op
once settled), but it holds the event loop open for the whole window,
which under `node --test` is a suite lingering seconds for nothing.

That implies something the comment did not say, and it had already bitten
this PR: if `markerAt` can be set after the exit was observed, any wording
derived from observation ORDER is unstable. The old message read
"rendered at Nms and then exited Mms later", where M was
`since() - markerAt` evaluated at finish — not the paint-to-exit gap at
all, and incoherent whenever the marker surfaced during the drain. The
test asserted on /survival window/, which the losing side of that race
could drop. It could have flaked, and the flake would have looked like
the bug this PR fixes.

So the message now makes no ordering claim and reports both times as the
observations they are, with `exitAt` captured in the exit handler rather
than recomputed later. Assertions moved to the race-stable phrase, plus a
test that runs the paint-then-die stub 12x asserting verdict AND wording
are identical every time — one pass proves nothing about a race.

The ordering could not be forced on darwin, so the guard is reasoned
rather than reproduced, and the reply says so. Two attempts and what they
actually showed: a 4MB payload with the marker last never gets there,
because `process.exit()` discards pending stdout writes (the "before
rendering" branch is correctly taken); marker on stderr with a graceful
exitCode was observed first in all 30 runs, none lingering near the
window. `done()` exists precisely because exit and close are separate
events, so treating their order as guaranteed was worth removing anyway.

Also (suppressed comment): the README's "Two more do the same" clause now
lists four suites, not two, after this PR added render-smoke and pty.

747f59892f fix(scripts): disarm the first-paint deadline once the marker is seen (#2147)
Copilot review round 3.

`done()` is first-caller-wins, and the render deadline stayed armed after
first paint. So a marker landing near `timeoutMs` let that timer fire
*inside* the survival window and settle the run as

    child did not render "MCP Servers" within 15000ms

followed by an output tail that visibly contains "MCP Servers". A TUI that
is merely slow fails intermittently, with a diagnostic naming the one
thing that demonstrably did happen — the same wrong-attribution class this
PR exists to remove, and one that reads as flake.

First paint has happened; its deadline no longer has a question to ask, so
`onData` clears it at the moment the marker is observed.

Also hoists `renderTimer`'s declaration beside `surviveTimer`'s. It was a
`const` below both closures that clear it, safe only because `onData` and
`done` run from events rather than the synchronous body. That already held
for `done`; this fix adds a second reader, so the ordering is now stated
rather than relied upon.

The test paints at 250ms with timeoutMs 400 and surviveMs 400, so the
render deadline expires while the survival window is open — the exact
shape. Verified it fails against the module with the clearTimeout removed
and passes with it: a wider timeoutMs would have been green either way,
which is why the numbers are tight.

b7a73e7da3 fix(scripts): address Copilot review round 2 on #2147
Two findings, both of which quietly undo the PR.

1. `SMOKE_TUI_SURVIVE_MS` was unvalidated. `??` guards only nullish, so
   an env var set to the empty string reaches `Number("")` -> 0 and a typo
   reaches NaN; `setTimeout` fires immediately on both. The survival check
   would then resolve before the child could possibly have died, printing
   "still running 0ms later" and asserting nothing — the exact first-paint
   false green this PR removes, restored by an empty environment variable,
   on a green run.

   Fixed at the module rather than only at the env-parse site, so every
   caller is covered: `normalizeMs` (same shape as child-cleanup.mjs's
   `normalizeGraceMs`, matching an existing policy rather than inventing a
   second one) applied to all four durations before anything reads them,
   which also stops the messages interpolating "NaNms". Defaults moved to
   an exported DEFAULTS so the smoke and the module cannot drift.

   `surviveMs: 0` is deliberately NOT honored as "skip the wait": no
   caller wants that, and it is indistinguishable from the typo.

2. (suppressed comment) `spawnSync` REPORTS ENOENT in `result.error` — it
   does not throw — so `probeScriptVersion`'s try/catch read a missing
   binary as "ran, printed nothing". On linux that empty output fell
   through to the util-linux guess, and the smoke then hard-failed
   spawning a binary that does not exist instead of taking the documented
   skip.

   `probeScriptVersion` now returns `{ available, output }`, and
   `resolvePtyWrapper` returns `{ ok: true, flavor, wrap }` or
   `{ ok: false, reason }` — the two unavailability causes deserve
   different skip messages, since "no script(1) on PATH" and "nobody has
   verified this platform's invocation" send the reader elsewhere. A
   non-zero exit is explicitly not unavailability: BSD `script` has no
   `--version` and answers with its usage, which is the evidence the
   flavor fallback reads.

Tests for both, since each finding lives entirely in a branch no happy
path reaches: the normalizeMs table (empty string, typo, undefined, -1,
Infinity, a numeric string, 0), an end-to-end run proving a
`surviveMs: Number("")` paint-then-die stub still fails, the
`result.error` ENOENT and timeout shapes, and both `resolvePtyWrapper`
failure reasons.

Verified: `SMOKE_TUI_SURVIVE_MS="" npm run smoke:tui` reports "still
running 2000ms later"; with PATH blanked, resolvePtyWrapper returns
`{ok: false, reason: "no `script(1)` on PATH"}` rather than guessing.

bd7297da88 fix(scripts): address Copilot review round 1 on #2147
- pty.mjs: narrow the BSD argv set to {darwin, freebsd}. Grouping every
  BSD together was wrong — NetBSD's `script` takes the command through
  `-c`, so the argv form fails at `script` startup, which this smoke would
  then report as a TUI crash. Rather than add an unverified `-c` branch
  for netbsd/openbsd, they fall through to `null` and the smoke skips with
  the reason: a guessed invocation turns a clean skip into a false failure
  while looking like support.

- pty.test.mjs: "supported unless Windows" would fail `test:scripts` on
  aix/sunos/netbsd/openbsd, where a null wrapper is correct and the smoke
  skips by design. State the policy once (SUPPORTED_PLATFORMS) and branch
  on it, keeping the real-probe teeth that catch a `script` missing from
  PATH. Pin netbsd/openbsd/aix/sunos to null in scriptFlavorFor's tests
  so "unsupported" reads as the default, not a win32 special case.

- render-smoke.mjs: the @returns contract claimed a close guarantee the
  code does not give — both drain give-up branches resolve after only a
  warning, so output can be truncated and the child may still hold the
  work dir. Document the bounded fallback and name the required cleanup
  shape (removeSafe, not rmSync), since a caller "tightening" cleanup on
  the old wording would reintroduce #1801 exactly where it doesn't hold.

- AGENTS.md, clients/launcher/README.md: drop the pre-#2111 claim that the
  smokes build test-servers "on demand if it is missing". ensureTestServers
  rebuilds unconditionally, once per process — presence is not freshness.

- .github/copilot-instructions.md: mirror the survival rule, per the
  same-PR mirroring requirement. One bullet, generalized past this fix:
  a smoke must assert the thing survives, not that it started, and the
  started-then-died branch belongs in a scripts/lib test against a stub.

b6baa30d7b fix(scripts): make smoke:tui assert the TUI survives its first frame (#2147)
`smoke:tui` spawned the launcher with `stdio: ["ignore", …]`, waited for
"MCP Servers" in the output, printed OK, and SIGTERMed. It never looked at
the child again.

The child was already dead. Ink mounts `useInput`, `useInput` needs raw
mode, and raw mode is a property of the file descriptor — with stdin on
/dev/null the TUI painted one frame and exited 1 about 40ms later with
"Raw mode is not supported on the current process.stdin". Measured here:
first frame at 396ms, exit 1 at 433ms. The smoke won that race and
reported success, so what it asserted was *first paint*, not survival —
contradicting its own header ("boots and renders without crashing").

This is not environment-specific: `stdio: ["ignore", …]` makes the child's
stdin /dev/null whether or not the developer's terminal is a TTY, so this
smoke has never verified a running TUI on any machine. And the race cut
both ways — an `exit` processed first failed the run, which reads as flake
rather than as the standing defect.

Two pieces:

- `scripts/lib/pty.mjs` gives the child a real terminal via `script(1)`,
  no dependency. The three flavors are not interchangeable (BSD takes
  argv; util-linux takes one shell string plus `-e`; busybox that string
  without `-e`), so the invocation is built and unit-tested rather than
  written inline. A platform with no `script(1)` skips loudly instead of
  running without one, which would be a guaranteed failure rather than a
  weaker check.

- `scripts/lib/render-smoke.mjs` is the fix: the child must still be
  running `surviveMs` (default 2s) after first paint. Without that, a
  future harness change reintroduces the same false green and nothing
  notices — which is why it lives in a module `test:scripts` drives
  against a stub that paints the marker and immediately exits. Today's
  harness passes that stub; this one fails it, with a diagnostic that
  distinguishes "died after painting" from "died before painting".

The smoke additionally fails if the raw-mode error appears in a passing
run, so a future Ink that degrades to a warning instead of throwing can't
ship a TUI with no keyboard input past this gate.

Verified end to end: with a `script` shim that allocates no pty, the smoke
now fails with "it painted one frame, it did not run"; with the real one
the TUI is still running 2s after its first frame and never logs the
raw-mode error.

The `process.env.CI` skip stays, but its comment is corrected: the PTY
removes the technical blocker it used to cite, so the smoke is local-only
by decision now, not by capability. Whether it joins GitHub CI is out of
scope here (#2146 is keeping the other local-only smokes out on purpose).

dc026acfea chore(web): drop the double cast from the useSessionRef test fixture
Addresses Copilot's review on #2152. The client stand-in was
`({ tag }) as unknown as InspectorClient` — a double cast with no
justification, which AGENTS.md rejects.

`Object.create(InspectorClient.prototype)` gives a real prototype chain
without running the constructor, so it needs only a single cast and still
drags in no transport or environment. The tag went with it: every
assertion compares identity, and `Object.create` already returns a
distinct object per call.

104b3c0775 chore(web): collapse App.tsx's six session refs into useSessionRef (#2129)
Step 1 of phase 2 of the App.tsx decomposition, landed first and alone
because it is the seam the remaining clusters are extracted onto.

App.tsx kept six "latest value" refs so long-lived callbacks could read a
current value without listing it as a dependency and being re-created on
every change: `activeServerNameRef`, `activeServerIdRef`, `serversRef`,
`inspectorClientRef`, `pendingStepUpRef` and `pendingReauthRef`, plus the
three passive effects that synced them. `useSessionRef` replaces all nine
with one hook returning one stable ref onto a `SessionSnapshot`.

This is not a store: nothing renders off it, nothing subscribes to it, and
mutating it never schedules a render. It is not the prop-to-state sync
AGENTS.md forbids either — that rule is about `setState` in an effect, and
a ref write produces no render at all. It is exactly the pattern the file
already used, written once instead of six times.

What it buys the later steps is a *stable* dependency: a hook taking
`sessionRef` does not drag the other clusters into its argument list, so
`useOAuthRecovery`, `useConnectionLifecycle` and `useServerCommands` can
be extracted one PR at a time.

Behavior is unchanged:

- The snapshot is seeded from the first render's values, matching what
  each `useRef(value)` seeded.
- `activeServerName` keeps its one non-uniform rule — it holds the last
  server that *was* active and is never cleared, because a transport
  crash clears `activeServerId` before the failure toast is raised. It is
  derived from `servers`/`activeServerId` rather than taking the
  `activeServer` memo, which is the same value by definition and is what
  lets the hook be called ahead of that memo.
- The two pending-* syncs already ran ahead of the only effect that reads
  them, so merging them changes no effect's view. The other four synced
  below every effect that reads them, so hoisting that sync changes none
  either.
- The sync effect is deliberately un-gated rather than carrying a
  dependency list: re-assigning unchanged values costs nothing and
  removes a place for a newly-added field to be forgotten.

`sessionRef` is declared ahead of its first reader because a hook return
is not provably stable to `react-hooks/exhaustive-deps` — consumers must
list it, and a later declaration would put every one of them in the
temporal dead zone. Listing a ref that never changes identity re-runs
nothing.

The inline `pendingStepUp` state shape is named `PendingStepUp` and moved
beside `StepUpSource` in `utils/stepUp.ts`, so the snapshot can name it
without importing from the component that owns the state.

2fca87c0ad chore(web): record the useProgressToasts return-type exception
Copilot's second pass accepted every code fix and re-raised one item:
useProgressToasts is the only extracted hook that returns nothing, which
contradicts #2128's "each hook returns one object" criterion, and the
disagreement was recorded nowhere a reader would find it.

Its ask was either a result object or an explicit exception. Taking the
second: the hook subscribes, shows toasts and unsubscribes, and the only
state it owns is toast-id bookkeeping the caller must not see, so `{}`
would advertise an API that is not there. The criterion exists to stop a
hook handing back a long list of loose values — useTabUiState's
twenty-two is the case it was written against, and that one does return
a bundled object.

Noted in the hook's own doc block (so it reads as a decision rather than
an oversight) and on #2128 itself, so the acceptance criteria and the
implementation agree.

edac58e304 chore(web): address Copilot review on #2128
Seven of the eight comments, plus the three suppressed ones (the same
double-cast class):

- Narrow the toast hooks to `InspectorClientEventSource`, the client's
  typed event-listener surface. A bare `EventTarget` cannot satisfy it
  (its listener takes an `Event`, the typed one a `TypedEventGeneric`
  with `detail`), so both tests now construct a real
  `InspectorClientEventTarget` and dispatch through `dispatchTypedEvent`
  rather than casting a stand-in. That failed to compile immediately and
  caught two bad fixtures: `task()` was a `Pick<Task, "status">` where
  the event map wants a full `Task`, and `toolCallTaskUpdated` was
  dispatched with no `task` at all.
- Narrow `useExportActions`'s three store parameters to the single
  clearing method each handler calls, so the test doubles are
  structurally checked instead of cast away.
- Build real `MessageEntry` fixtures (`timestamp` is a `Date`, not `0`),
  removing four more double casts.
- Fix a tautological assertion in useTabUiState.test: it compared a
  callback to itself, so it held however the identity changed. Every
  callback is now captured before the update and compared to those
  references.
- Reword `resetTabUiState`'s doc: `exhaustive-deps` cannot infer
  stability across a hook boundary, so the dependency IS named — the
  stability buys no churn, not omission.
- Justify the one remaining double cast in place, per the type-safety
  rule.

`useProgressToasts` still returns `void` rather than an object,
deliberately: it has nothing to return, and `{}` would imply an API that
is not there. Noted on the PR as the one deviation from #2128's
"returns one object" criterion.

e42968ba78 chore(web): extract App.tsx's leaf hooks (#2128)
Phase 1 of #2126. Six hooks move out of `clients/web/src/App.tsx`, taking
its component body from 4,891 to 4,267 lines with no behavior change:

- useThemeToggle       — the light/dark toggle
- useTabUiState        — the nine per-screen `ui` objects, the active tab,
                         the pinned-Protocol ids, and the session reset
- useInspectorStores   — the twelve state managers as one create/destroy
                         lifecycle, their `core/react` hooks, and the
                         pagination-mode selection
- useExportActions     — the eleven Clear / Export / Replay handlers
- useProgressToasts    — `notifications/progress` toasts
- useTaskToasts        — task-status toasts, the cancel confirmation, the
                         taskId -> progress map, and the in-flight
                         tool-call taskId ref

Holding the stores in one slot collapses `setupClientForServer`'s and
`onConfirmRemove`'s dependency arrays from twelve entries to two stable
callbacks; `destroyStores` reads the live set through a ref mirror rather
than the state it also writes.

All six hooks are at 100% on all four coverage dimensions, no `v8 ignore`
needed. Also refreshes the now-stale "~4.5k-line" description of App.tsx
in AGENTS.md and the coverage `include` comment.

4b119c9a95 chore(web): address Copilot review on #2127
- Move REPLAYABLE_PROTOCOL_METHODS / isReplayableProtocolMethod out of
  components/groups/protocolUtils.ts into utils/replayableProtocolMethods.ts.
  It is a pure predicate over a string set, so by the project's own lib-vs-utils
  rule it never belonged under components/ — and keeping it there was what made
  lib/protocolReplay.ts import 'up' into the component graph. Both consumers now
  import from utils/; the predicate keeps its own test.

- Give replayProtocolRequest an exported ReplayClient = Pick<InspectorClient, ...>
  naming the nine methods it calls, so a caller (and the test) can satisfy the
  real contract instead of casting a stub into a whole client.

- Rebuild the protocolReplay fixtures as plain typed MessageEntry values. The
  double cast had been hiding a real defect: MessageEntry.timestamp is a Date
  and the fixture passed a number, so the assertion confirmed a shape
  messagesToLogEntries cannot produce.

- Replace the window casts in authToken.test.ts with Reflect.set /
  Reflect.deleteProperty. No 'as unknown as' remains in either test.

- Drop the stale 'floats top-right' sentence on ReAuthBannerBar, which moved
  verbatim and arrived contradicting the paragraph below it.

Declined: re-homing ReAuthBannerBar's transform/zIndex as a theme variant.
'styles' is the Styles API rather than an inline style, Mantine exposes neither
property as a prop, and a styling change is out of scope for a phase whose
safety argument is that nothing was edited.

b6ed5072f4 chore(web): move App.tsx's module-level block into files (#2127)
Phase 0 of #2126. Lines 239-668 of clients/web/src/App.tsx were already at
module scope — helpers, formatters, constants, and the toast subcomponents,
none of which close over component state — so the whole block moves verbatim
into files. App.tsx drops from 5,303 to 4,892 lines with no behavior change.

Placement follows the lib-vs-utils rule in AGENTS.md: pure computation to
utils/, anything touching the environment to lib/.

EMPTY_SETTINGS and the two loose toast ids deliberately do NOT land in a new
top-level src/constants.ts, which the issue suggested: the web coverage
include is a whitelist naming components/hooks/theme/lib/utils/server, so a
module there would have fallen out of the >=90 gate silently. They go under
utils/ instead.

ReAuthBannerBar is in the block but not in the issue's table — it was added
after the issue was written (#2108). It moves to components/groups/ReAuthBanner/,
beside the banner it wraps.

Every new module is at 100% on all four coverage dimensions. Two v8 ignores,
each justified in place: getAuthToken's typeof-window guard (a happy-dom
inherent path) and replayProtocolRequest's provably-dead default case.

e0ecf58df3 fix: address Copilot review round 42 — let an optional const be opted into
Making every pinned field read-only left an optional one unreachable: the
schema is equally happy with or without it, but the form displayed a value the
user could neither send nor edit. An optional `const` is a yes/no rather than
a fixed answer, so it renders as its single choice, clearable — opting in sends
the schema's own typed value, opting out leaves the property absent. A required
one is still displayed read-only, since there is nothing to decide.

b0b252a5c0 fix: address Copilot review round 41 — const does not demand a property, required-only branches
- `const` constrains a property that is PRESENT; it neither requires the
  property nor acts as a default. It is now supplied automatically only where
  the schema also requires the field — in `collectSchemaDefaults`,
  `applySchemaConstants` and the TUI's initial values alike — so an optional
  `dryRun: { const: true }` no longer turns a valid `{}` call into one that
  asks the server to do something. A value that IS present is still corrected
  to the constant, whatever supplied it, and the field stays read-only.
- Offerability is judged on the base+member merge rather than the raw member,
  so `anyOf: [{ required: ["email"] }, { required: ["phone"] }]` over
  root-declared properties is offered. It was declined, which left the gate
  checking the base alone and accepting `{}` — which that schema rejects.
- The TUI's branch sections keep the schema's own `required` for the seeding
  decision while still rendering every branch field non-required, which is what
  keeps a static form submittable.

48651956e5 fix: address Copilot review round 39 — identify branches by their schemas, cover the deep-link path
- branchesKey is built from the resolved alternatives themselves, not from
  labels and field names: two branches can share both while pinning different
  discriminators or typing a field differently, and a reorder of those went
  unnoticed — the form then displayed one branch and submitted another.
- InspectorView gains a deep-link test with root-union appArgs: they name the
  second branch, and the assertions pin the picker, the read-only
  discriminator, THAT branch's default (not the first branch's), and the
  absence of the other branch's field. The old shallow spread fails it.

of different types are ambiguous, and the raw string the user typed is the

85b030cbde fix: address Copilot review round 37 — stale constants, inherited answers, prefixed labels
- The seeding effect re-applies constants as well as filling absences: an
  in-place schema change can move a `const` the user cannot edit, and the
  read-only field then displayed the new value while `values` still held the
  old one — which is what would be submitted. Ordinary defaults are still only
  ever added, so an edited field keeps what the user put there.
- hasMissingIn checks own-property presence: a required argument legally named
  `constructor` resolved to the inherited one and read as supplied, enabling
  a submit the schema rejects.
- The TUI keeps the declared name as a branch field's fallback title. The
  prefix is an internal field NAME, and buildFields labels from its map key —
  so the showcase displayed `__b0__address` where the schema says
  `address`.

139563f720 fix: address Copilot review round 35 — reseed on an in-place schema change, label every primitive const
- The seeding effect is keyed by the fixed values themselves as well as the
  entity and branch. A tool refreshed in place keeps its `resetKey` and its
  branch while its schema changes underneath, so a newly pinned field was
  rendered read-only and never seeded — leaving a required one permanently
  unsubmittable. The schema object's identity says nothing (callers rebuild it
  every render), which is why the key is derived from what has to be seeded.
- branchLabel stringifies every primitive constant. `hasDiscriminator`
  accepts distinct booleans and nulls, so a `true`/`false` union was
  discriminated perfectly well and still labelled "Option 1"/"Option 2".

ba91db97e2 fix: address Copilot review round 34 — structured constants, non-required const controls
- A `const` may be an object or an array, with or without a `type`, and
  `String({...})` is "[object Object]" — which no CLI argument can equal, so
  the only value such a schema accepts never matched. Supplied text is parsed
  and compared structurally through the resolver's own comparison (exported as
  `sameJsonValue` so the two cannot disagree), for both branch selection and
  the substitution.
- The TUI's one-option const control is never marked required: its option may
  legitimately be the empty string, which ink-form's required gate can never
  accept, so submission would not even reach `decodeFormValues`. The value is
  fixed by the schema, and `missingRequiredFields` still validates the call.

00d9905781 fix: address Copilot review round 32 — normalize before the type vote, enum-spelled null
- coercionProperties collapses each declaration before comparing types. A
  nullable schema written as an `anyOf` states no top-level `type`, so
  `number | null` and `boolean | null` both read as "no type" and counted
  as agreeing — and `value=true` then came back as `NaN` through the first
  branch's number.
- admitsNull reads an `enum` offering null, under the same sibling conditions
  a `const: null` answers to. Without it `{ enum: [null] }` reported that it
  rejects null, and a required read-only field spelled that way stayed
  permanently invalid.

c9162d0e73 fix: address Copilot review round 31 — proto-safe results, set-valued types, core keywords
- convertToolParameters defines its result keys rather than assigning them, so
  a discriminator legally named `__proto__` reaches the call instead of the
  prototype setter. It also collapses a nullable declaration before dispatching,
  so `type: ["number","null"]` coerces as a number rather than being sent
  as text.
- typeNameOf sorts an array `type`: JSON Schema reads it as a SET, so
  `["number","null"]` and `["null","number"]` are one declaration
  and must not read as branches disagreeing.
- nullableUnion's non-asserting keyword set covers `$defs`, `$id`,
  `$schema`, `$anchor`, `$dynamicAnchor` and `$vocabulary` — they
  identify or declare rather than assert. `$ref` stays out: it applies
  whatever it points at.

67e7a4ca1a fix: address Copilot review round 30 — seed a read-only const for callers that do not
Rendering every `const` read-only assumed the caller had already seeded it,
which SchemaForm never did itself: `InlineElicitationRequest` passes its
values straight through and gates submit on hasMissingRequiredFields, so a
required `const` — a root union's discriminator among them — was displayed
and never supplied, leaving Submit disabled with no way to fix it.

The form now reports the fixed values upward once per entity, in an effect (the
parent's `onChange` cannot be called during our render), adding only names
absent from `values` — so a caller that already seeds sees no call at all and
the report cannot loop.

86c143fd0d docs(smoke): point each smoke's on-demand example at its own command
smoke-web-elicitation.mjs told the reader to run
`SMOKE_BROWSER=webkit npm run smoke:web:app` -- the App smoke, not the
elicitation smoke the file documents. Following it exercises a different
path entirely, and it does not fail while doing so: a real smoke runs and
passes, so nothing signals that you never tested what you were reading
about.

This is a direct cost of my own decision two rounds ago to make the two
App headers word-for-word identical so they could not drift. The shared
PROSE should be identical; the example command is the one line that must
not be, and copy-paste does not distinguish them. Both headers now name
their own smoke, and both point at npm run smoke:web:webkit for all three.

Guarded, since the class is invisible at runtime by construction:
run-engine-smokes.test.mjs now asserts no smoke header tells the reader to
run a sibling's command, and that every `npm run` it does name is a real
script. Both mutation-verified -- restoring the exact bug fails the first,
and naming a nonexistent script fails the second.
